How to use the prompt tool in

Bootstrap? The following article will introduce to you the usage of pop-up prompts and tooltip components in Bootstrap5. I hope it will be helpful to you!

Let’s talk about two controls: Popovers and Tooltips. These two components have a single function and are very simple to use. Lots of similarities. [Related recommendations: "bootstrap Tutorial"]

Popovers

1 Example

1.1 Notes

Things to note when using the popover plug-in:

It must rely on bootstrap.bundle.min.js to work!
For performance reasons, popovers are optional, so you must initialize them yourself.

1.2 Enable popovers everywhere

One way to initialize all popovers on the page is to select them via their data-bs-toggle attribute:

<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="keywords" content="">
    <meta name="description" content="">
    <link href="../bootstrap5/bootstrap.min.css" rel="stylesheet">
    <title>Popovers</title>
  </head>
  <body>
    <div>
        <br><br><br><br>
        <button type="button" 
            class="btn btn-lg btn-danger" 
            data-bs-toggle="popover" 
            title="提示标题" 
            data-bs-content="你想告诉别人些什么提示？你可以写在这里！">
            点此按钮弹出提示
        </button>
        
      </div>
     <script src="../bootstrap5/bootstrap.bundle.min.js" ></script>
     <script>
        var popoverTriggerList = [].slice.call(document.querySelectorAll(&#39;[data-bs-toggle="popover"]&#39;))
        var popoverList = popoverTriggerList.map(function (popoverTriggerEl) {
        return new bootstrap.Popover(popoverTriggerEl)
        })
     </script>
  </body>
</html>

1.3 Using container options

When certain styles on the parent element interfere with the popover, you need to specify a custom container , so that the popover's HTML is displayed in that element. There is no difference in display between this one and the above one, except that an example-popover is added to the button class.

<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="keywords" content="">
    <meta name="description" content="">
    <link href="../bootstrap5/bootstrap.min.css" rel="stylesheet">
    <title>Popovers</title>
  </head>
  <body>
    <div>
        <br><br><br><br>
        <button type="button" 
            class="btn btn-lg btn-danger example-popover" 
            data-bs-toggle="popover" 
            title="提示标题" 
            data-bs-content="你想告诉别人些什么提示？你可以写在这里！">
            点此按钮弹出提示
        </button>
        
      </div>
     <script src="../bootstrap5/bootstrap.bundle.min.js" ></script>
     <script>
        var popover = new bootstrap.Popover(document.querySelector(&#39;.example-popover&#39;), {
            container: &#39;body&#39;
            })
     </script>
  </body>
</html>

You can also use id, which seems more understandable

<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="keywords" content="">
    <meta name="description" content="">
    <link href="../bootstrap5/bootstrap.min.css" rel="stylesheet">
    <title>Popovers</title>
  </head>
  <body>
    <div>
        <br><br><br><br>
        <button type="button" 
            id="example-popover"    
            class="btn btn-lg btn-danger" 
            data-bs-toggle="popover" 
            title="提示标题" 
            data-bs-content="你想告诉别人些什么提示？你可以写在这里！">
            点此按钮弹出提示
        </button>
      </div>
     <script src="../bootstrap5/bootstrap.bundle.min.js" ></script>
     <script>
        var popover = new bootstrap.Popover(document.querySelector(&#39;#example-popover&#39;), {
            container: &#39;body&#39;
            })
     </script>
  </body>
</html>

2 Change the pop-up direction

us You can make the pop-up prompt information in four directions: top, right, bottom, left. It is also very simple to use. You only need to add data-bs-placement="position" to the button attribute, where the position can be top, bottom, left, or right.

It should be noted that the position to be displayed must have enough space, otherwise, it will automatically find a suitable position. If you set it to be displayed at the top, but it is already at the top of the browser, it will Shown below.

3 Close again anywhere

By default, click the button to display the prompt message , click this button again to hide the message, otherwise the message will always be displayed. If we want to click anywhere again to close the previously displayed prompt information, we need to add a data-bs-trigger="focus" attribute to the button, and add trigger: 'focus to the js file '.

To achieve correct cross-browser and cross-platform behavior, the a tag must be used instead of the button tag, and the tabindex attribute must also be included.

Tooltips

Tooltips are very similar to Popovers and can also be If you choose to load it, you must initialize it yourself. Its display will also be Automatically adjust according to reserved space. Different from pop-up tips, tool tips will be displayed when the mouse hovers over the button, and will automatically hide when the mouse is moved away, without the need to click.

1 The tool tip validation code

is basically similar to the pop-up prompt. This code must be included in the page for the tool tip to take effect.

var tooltipTriggerList = [].slice.call(document.querySelectorAll(&#39;[data-bs-toggle="tooltip"]&#39;))
var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) {
return new bootstrap.Tooltip(tooltipTriggerEl)
})

2 Tool tip example

Tool tips are generally used on buttons and links to explain their functions. Of course, they can also be used on on the picture. The value of title is the content displayed when the mouse is hovering, and you can use html elements.

The link has a default title attribute, and its prompt text is displayed in the browser status bar. This display is more intuitive.
